The stenomap comprises a series of smoothly curving linear glyphs that each represent both the boundary and the area of a polygon. We present an efficient algorithm to automatically generate these open, C1-continuous splines from a set of input polygons. Feature points of the input polygons are detected using the medial axis to maintain important shape properties. We use dynamic programming to compute a planar non-intersecting spline representing each polygon's base shape. The results are stylised glyphs whose appearance may be parameterised and that offer new possibilities in the 'cartographic design space'. We compare our glyphs with existing forms of geometric schematisation and discuss their relative merits and shortcomings. We describe several use cases including the depiction of uncertain model data in the form of hurricane track forecasting; minimal ink thematic mapping; and the depiction of continuous statistical data. dates_date: 2014-12-01 dates_date_type: published publication: IEEE Transactions on Visualization and Computer Graphics volume: 20 number: 12 publisher: Institute of Electrical and Electronics Engineers (IEEE) pagerange: 2053-2062 id_number: 10.1109/tvcg.2014.2346274 refereed: TRUE issn: 1077-2626 citation_doi: 10.1109/tvcg.2014.2346274 citation: Van Goethem, A., Reimer, A., Speckmann, B. & Wood, J. view all authorsEPJS_limit_names_shown_load( 'creators_name_14151_et_al', 'creators_name_14151_rest' ); (2014).
